How to connect?

Pontiac's Oakland County Michigan setting features oak, maple, and hickory as the main tree pollen sources, with exposure varying between the wooded Clinton River headwaters residential areas and the more built-up commercial corridors along Woodward Avenue. The Clinton River corridor provides locally significant green space, while the numerous Oakland County lakes create temperature-modifying microhabitats and the residential woodland in older neighborhoods contributes locally significant tree pollen.

How often is the Pontiac pollen forecast updated?

The Pontiac pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Pontiac come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Pontiac based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Pontiac, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
